Family-based treatment in adolescents and individual psychoeducation in adults are accepted components in a multimodal treatment of eating disorders. However, only few studies have been conducted on the use of parent-based psychoeducation. This paper presents the structure and content, as well as a preliminary evaluation, of a group psychoeducation program for parents of adolescent patients with eating disorders. The program is limited to five 90-minute sessions and aimed at increasing the parents' understanding of the disorder and promoting high transparency with regard to our treatment principles. The vast majority of parents rated the group psychoeducation as helpful in coping with their child's disorder and would recommend others to take part in the program.
